I've bought simple 0.3Pa vacuum pump which seemed to be reliable. I've pumped the air out until the glow turned to dim blue. Then I've cut close using standard torch. It's amazing! I feel the video doesn't show how really beautiful it is. 

Another interesting thing is how glow change when tube depressurized. The color change from dim blue to red through white bright 

Note: Most of sites/video like jdflyback and simplifier use metal to glass connection. I was not able to make one which not leaked. Instead I've used different heat resisstent glue. It is success and was not leaked yet.
